- Abstract:
- ?The performance of low level soymeal(msoymeal/m soybean oil=10%)in catalyzing the hydroperoxidation reaction using soybean oil as substrate was evaluated,and surfactants as well as ultrasonic wave were introduced to improve the lipoxygenation reaction yield.The optimal conditions for soybean oil were 0.5 g soybean oil in 3.3 mL phosphate buffer solution of pH6 with 0.15 mL ethanol as cosolvent reacting for 3 h at 15℃.Under those optimal conditions the yield reached 12%.The addition of surfactants such as CTAB and β-CD reduced the hydroperoxide yield.The employment of ultrasonic wave(100 W,40 Hz)during the aerobic catalysis reached equilibrium after 60 min with the yield of 35%,which could both accelerate the enzymatic reaction and improve the reaction yield.
